Oil metering pumps and injectors don't work like it seems some think.
Read jpgs attached.
Oil does NOT go thru/past the rubber check valve at the top of the injector.
Blowing and sucking at one end or the other does not determine if the path of the oil is blocked inside the injector.
Vacuum is only seen at the BOTTOM of the injectors. The top gets what the attached jpg says..............bleed air like the bleed air for fuel injectors. Not vacuum, please.
